NYC’s Recent Blackout Highlights the Importance of Properly Functioning Relay Protection Systems
New York cities’ recent blackout didn’t go unnoticed by many in the utility industry. A substation relay protection system did not operate as it was designed causing 74k customers to lose service. Do you know if your system is at risk?
System protection engineering strategies are critical to ensure that a utility provides safe, reliable electric power. These are often overlooked until something goes wrong, and this neglect can come at a cost.

- Ground Overcurrent Relaying and High-Resistive Ground Faults.
- Problems can result if these are not properly accounted for.
- The importance of substation relay coordination, regardless of how substation jurisdiction is divided.
- The importance of coordinating relays within a substation, between substations, and with neighboring utilities, and the problems that can occur.
- The importance of verifying your relay settings are up-to-date, accurate, and coordinated, including your downstream devices.
- Issues that can arise if this coordination does not take place.
- The importance of having complete, accurate, and up-to-date substation drawings, and the need for these drawings to properly set and coordinate relays.
- Risks that can take place if drawings are not updated properly.
